I can't find the post this morning. Yesterday someone was looking for a PDA kind of device that he could use in business to store data. A suggestion occurred to me last night. I have a simple Kindle Touch which I bought for about $70. With free apps from the Amazon store I use it to keep phone numbers, number lists, passwords. It has a calculator, a timer/stopwatch, a good calendar. It's very small, light and efficient without too much fancy stuff. It doesn't access the internet well (except to download books and apps), but it plays games and audio files. It's a great and undemanding tablet.
